too early to have anything of any real weight in the packs, but a good age to get him used to wearing it. and plan for short walks because his joints arent done growing. gradually make the wlaks longer.

lol, no question is stupid, as long as it is sincere and you learn something by asking it.
start walking him the day you get him. plan for short walk/hikes (1/2 mile?), and turn around before he/she gets tired. gradually make the walks longer. say first week or two, maybe 3 go 1/2 mile. next coulpe weeks go 3/4 mile. get him used to a back pack but remember, he wont stop growing untill he is between 12 and 24 months. after 12 months theres some growing but usually not noticable. walk him around with an empty pack, maybe let him wear it for a half hour or so in the house too now and then. once hes fully grown he should be used to the pack enough and obedience trained enough that you can put some of his food into his packs and go camping or hiking. as to how far to hike at a time...you will be able to tell from your previous walks and hikes. if the farthest he has ever gone round trip is 4 miles and he was worn out, dont expect him to go 6 miles on a hiking trip. remember not to have him carry water, and to keep his packs evenly filled. (this isnt the max he can carry, or how much he will eat, just an example) if you start with 2 pounds of food on on side, and 2 pounds of the other. then you stop to camp for the night and feed him one pound from one side. take 1/2 a pound out of the other side, and put it back into the side you just fed him from. if the packs get uneven they will rub and cause wounds, similar to rope burn.

I diagree with Stirder... You should really not take your dog in public places until he has his full sets of shots. Any dog with parvo walking on the pavement could leave the virus there, and your dog can catch it until he's totally vaccinated.

I wasnt very clear was I??? sorry for that. I didnt mean to take an unvaccinated dog out on any of those activities. I meant once he/she is fully vaccinated (done with the frequent puppy shots) to start preparing for the backpacking trips, and training with the 1/2 mile walks etc.
